Making the stand alone arduino is a great way to learn more about the µcontroller (microcontroller) that powers the official Arduino µcontroller as its the brains that controls all the inputs & outputs, data processing, etc. of the controller. While using an official Arduino (the capitalized ‘a’) or clone is useful, the experience isn’t the same as building, programming, & completing your own. An official Arduino costs $22, a clone costs $10, which is cheaper, but doesn’t compare to the $4 expense needed to assemble your own. An added benefit is that the chip is an easy $2 replacement if you happen to burn it out, which will happen often as you start your arduino journey.
